Wondering the same thing - What was the slow part, reading from Mongo or writing to Postgres? It should not be the latter, unless there are a lot of indexes that were not dropped before the bulk load, or the ETL works one...row...at...a...time... Even a simple 'mongoexport --csv | psql -c "COPY FROM stdin"' should faster for 50M records.
